Regarding the ins and outs of what Zhang Jian told Zhang Lu, according to Zhang Lu's personal understanding, after adding some basic knowledge and vocabulary concepts from before the crossing, it is roughly like this:

After ascending to immortals, the original mortals have been reborn in both physical and conscious terms, living in the vast heavenly realm, without birth, old age, sickness and death, without grievances and entanglements, enjoying joy and longevity, in fact, there is no need for any leader at all. www.biquge.info It is said that the previous generation also respected the Xuanyuan Yellow Emperor, but although the Yellow Emperor was shorter than Chi Songzi and Rong Chengzi, he was highly respected, and when the big guys had something to gather, they were able to sit in the chief, and that's all, they could be regarded as "the head of the immortals", but not the "Lord of Heaven".

It's only in the last three or five hundred years -- this is in terms of time on earth, and the flow of time in the heavens is naturally different from that on earth, and there is no movement of the sun and moon (the red sun hanging in Liu Lei's residence is just an illusory image), so there will be no distinction between years, months, and days -- the immortals are suddenly threatened by the outside, so they are forced to elect a leader to come out and coordinate everything to resist foreign enemies.

If the earth and the heavens belong to different planes, then there is a third time and space outside the heavens, and it is a time and space that even the immortals are inexplicable. Some immortals speculate that the heavenly realm is higher than the earth (not in terms of location), and this third time and space is equivalent to the heavenly realm, according to the unreliable folk theory, it is the so-called ghost world, the underworld or the demon world;

However, there was no intersection between this third time and space and the heavenly realm, unlike the heavenly realm and the mortal realm, although mortals could not easily ascend to the immortal realm, immortals could go to the mortal realm as they wished - Zhang Jian is a good example. Therefore, the second speculation that has been refuted the most is: Although we can't reach the realm and can't fly again, then why didn't Gu Immortal and Yellow Emperor think of coming back to guide their juniors?

Yes, about three to five hundred years ago, suddenly there were many "gaps in the sky" in various parts of the heavenly realm, that is, one-way passages to another time and space. This passage is not open to the immortals, and many immortals have tried various methods to explore inside, but all of them have returned - either they can't get through at all, or they stick out a hand, and the hand will turn into ashes. However, there are some foreign objects that are formless and formless, and it is difficult to even sense them, and they have entered the heavenly realm through the gaps in the sky.

Much like what happened to Zhang Lu in the Fawang Temple, the immortals discovered some existences that didn't seem to exist at all, and where these non-existent existences flowed, not only did the illusions created by the immortals collapse instantly, but even the foundation of the heavenly realm, the pure and thick vitality, gradually shrank as if infected with disease. Because they don't know the reason and have no name, they used to call this foreign body "祟".

Some immortals believe that this kind of demon is from a foreign land, with the purpose of annihilating the existing universe, while others believe that it is not a conscious life form at all, but only a natural encroachment of a higher realm on this sub-realm. For example, if the heavenly realm is a thatched house, then it is a sudden gust of wind, which will destroy the hut, but the wind is unconscious, and the nature that produces the wind is also unconscious.

It's just that no matter what, the immortals can't sit still, but they must work together to resist this evil from outside the sky, so they promoted Liu Lei as the god of heaven and condensed the originally loose immortal society into a whole. After some hard work, the immortals finally eliminated the ghosts that invaded the heavenly realm one by one, but they could not block the heavenly gap, and there was still a steady stream of more ghosts pouring through the heavenly gap. This is always on the defensive, unable to attack, and the enemy seems to be endless, never ending, and sooner or later there is only one way to lose. And the immortals will think, I have cultivated for many years, and I have ascended to the immortal realm from mortals, I originally wanted to enjoy the blessings of immortals for a long time, could it be that I have a lifespan of tens of thousands of years or even longer, so I have to fight without seeing the future? When is it a game!

So they finally decided to elect a wise man to predict the future and find a solution.

As Xuan Jian explained to Zhang Lu not long ago, the way of divination also has its principle, everything has a cause and must have an effect, all causes are entangled, and all fruits converge, so that although the future is obscure, there is some context to follow. Of course, to calculate the future of the entire Heavenly Realm, let alone mortals, even ordinary immortals can't do it—or even if they do, they calculate one of the many possibilities for development, and the probability of achieving it is too low to be used as a guiding principle for action.

So in the end, many immortals gathered the immortal method in the body of a wise man to carry out an unprecedented big fortune calculation and prediction. The bad news is that if the problem of the Heavenly Gap cannot be solved, it will be 500 years at most, and not only the Heavenly Realm will be completely annihilated, but even the mortal world will be reduced to nothing - in a word, the world will be completely destroyed, and the good news is that there is no solution to the Heavenly Gap.

But what exactly is the solution? The wise man did not come up with a definite result, and only knew that the heavy responsibility would fall on the next cultivator who had ascended to immortal - note that it was the person who had not yet cultivated the Dao, not Pei Xuanren, who was already close to ascending to immortal. So the Heavenly Father ordered to send Zhang Jian to patrol the Nether Realm, visit the good immortal cultivators everywhere, guide them to the entrance, and urge them to ascend to the Heavenly Realm as soon as possible.

The reason why this task fell on Zhang Jian was because he ascended to immortality late, and he was still relatively familiar with the situation in the world - the Western Han Dynasty and the Eastern Han Dynasty were all Han Dynasty after all. If you let the Heavenly Father of the Xia Dynasty ascend to immortality...... This immortal, or sent the eastern prince and the western queen mother who ascended to immortal earlier, just pretending to be a mortal is not like it, the language, clothing, etiquette, social norms, and even some of the mountains and rivers are completely different.

Tiangong Liu Lei is not only the leader of the immortal princess, but also can be regarded as Zhang Jian's ancestor, since he has a fate, Zhang Thorn did not dare to disobey, so he went down to the mortal realm more than ten years ago and searched everywhere. Of course, a good seedling can't be seen at a glance, but also has to be observed closely, and even tested, which is the reason why he blended into the Langguan team and has been a colleague with Zhang Lu for so long.

According to Zhang Jian, since he descended to earth, he has found more than a dozen people, and among them, some of them have been eliminated in the process of cultivation -- for example, lack of talent and weak heart -- and finally only three people, including Zhang Lu, remain. In fact, Zhang Lu also belongs to a guy with a weak heart, he does not have enough desire for cultivation and immortality, and he has always been attached to the mortal world of flowers, the problem is that the origin is special and super strange, so Zhang Jian still keeps observing and refuses to give up lightly.

Then something happened, and Zhang Lu was attacked by Zhen. Theoretically, there is a gap between the world from which the world comes from and the heavenly realm, and the heavenly realm and the mortal world are almost open, and it is very easy for the mortal world to invade through the heavenly realm. But he has always invaded the heavenly realm, and refuses to set foot in the mortal world, as if he wants to eat one bite at a time, and if he doesn't swallow the heavenly realm first, he won't let down the chopsticks and move the mortal world in the bowl. Can it be said that it will intrude on the world? It cannot be said that there is no such thing as nothing, but the immortals have not clearly discovered it before, and Zhang Lu's experience can be said to be groundbreaking.

When Zhang Lu heard this, he couldn't help but ask: "Is that really a strange thing from outside the sky?" You haven't seen it with your own eyes, but you just listened to my description, can you be so sure? Zhang Jian nodded and said: "First Wuji and then Taiji, Taiji gives birth to two yi, transforms into four images, and causes all things." Therefore, everything exists, and those who are born without it are not what they do?"

According to Taoism, the universe was originally in a state of "infinity", with no center or boundary, no beginning and no end, no front and back, no front and back, no upper and lower left and right - to put it bluntly, it was a stage that only existed in theory, and did not even exist in abstract concepts.

After Wuji is Taiji, which is the original biochemical state of the universe, where there is no mixture and chaos. That is to say, nothingness is a concept that arises in correspondence with existence, existence and non-existence are one, there is no existence and no non-existence in the Wuji era, and there is also non-existence in the Taiji era. Then Taiji gave birth to the Yin and Yang two instruments, and the two instruments gave birth to the four images (the sun, the less yin, the less yang, and the Taiyin), and now this universe with mortal immortals, heaven and earth, time and space, was born from this.

Therefore, in this universe, everything exists, including physical living things, non-living things, and various concepts of imaginary fingers, which also belong to existence at the level of consciousness. Then a non-existent existence is actually a non-existent existence, and theoretically it is impossible to appear in this world. There has never been such a "thing" in the mortal world, and the only such "thing" found in the fairy world is the only one.

Zhang Jian said that even if your soul comes from two thousand years or another world, it is unlikely that you will deliberately make up such a non-existent existence to tease us and others - besides, as an immortal, can't you still see that what you are telling is the truth and a lie?

He has always only invaded the heavenly realm, and it is possible to harm the immortals - according to him, if the immortals come into direct contact with the immortals, they will be like reaching into the heavenly gap and annihilating them in an instant - but this time they went to the mortal world to attack you, then there is only one possibility: you are the natural enemy of the Emperor, and it is possible for us to solve the problem of the Emperor after you ascend to the Immortals, so the Emperor is trying to destroy you in advance.

Zhang Lu frowned: "In this way, Zhen is conscious and wise......"

Zhang Jian shook his head and said, "It's hard to say. Although it is the nature of a living person to seek advantage and avoid disadvantage, it cannot be denied that as long as it exists, it will have the inevitability of Tao. For example, when the water flows, it is not that the water consciously hates the water and that it must be filled, but that mortals do not understand the principle. Our knowledge of the Evil is very shallow, so we cannot conclude whether the attack on you is due to a conscious attempt to destroy you, or an unconscious action caused by some other mechanism. ”

Zhang Lu shrugged his shoulders, his thoughts suddenly jumped, and he asked a question that couldn't be hit with eight strokes: "How many immortals are there in the sky?"

Zhang Jian replied to him: "Not much, just more than a thousand." ”

"How many gaps are there?"

"Dozens. ”

"As you said, more than a thousand immortals are fully capable of blocking these dozens of heavenly gaps, right?"

"For the time being," Zhang Jian smiled bitterly, "but no one knows if there will be more gaps in the future, and whether there will be more spills coming from outside the sky." According to the results of the divination, we will either win or lose, and if we don't have your help, maybe in three to five hundred years, the heavenly realm will be annihilated. ”

"The Heavenly Realm is annihilated, but what about the immortals?"

"Or annihilation, or escape into the mortal world. However, it is very likely that after destroying the heavenly realm, he will destroy the mortal world, and then the immortals and mortals will become one and die out together......"

Zhang Lu couldn't help but shudder: "In this way, the heavenly realm is not peaceful, even if I work hard to cultivate immortals and ascend to the sky, I can't enjoy a happy life immediately, and I have to fight with Zhen first...... You are not afraid to say this, from now on to dispel my idea of cultivating immortals, honestly enjoy the life span of less than a hundred years in the world, and then close your eyes, regardless of the flood after death...... Regardless of this entire universe, will the two worlds of immortals and mortals be annihilated from now on?"

Zhang Jian smiled faintly: "No way, this is what you have to say to me, I can't make up nonsense to deceive you." And ......" he stared at Zhang Lu's eyes: "With your temperament, even in the world, you are not willing to live in obscurity and die without accomplishing anything, right? If you tell you that you have nothing to gain but to travel freely, you may have little interest in ascending to the immortal, and if you are told that you still have to fight, it may arouse your heart to work hard." ”

Zhang Lu tilted his mouth, and said in his heart, you really know me...... Indeed, deep in his heart, he vaguely felt that there was a higher level of pursuit, which was expected to soar again, or that there was an invasion of foreign enemies, and the immortal world where he had to struggle for survival was much more interesting than the heavenly world where he could live for 10,000 years without the suffering of birth, old age, sickness and death. It's just—"You also said that those who have life know how to seek advantage and avoid harm, and if I had been as fearless as you say, I would have gone down the mountain to step into the red world." The reason why he followed Pei Xuanren to cultivate in Zhongding for so many years is that after going down the mountain in the future, he will have a better chance to avoid disasters and achieve his goals. And I have almost no ability to defend myself now, and if you show me a target to fight it, I can dodge and escape every minute!"

Zhang Jian smiled: "It's useless to escape. If you are unconscious, you will not know that you have given up cultivating immortals, and you will still come to harm you; if you are conscious, you may not stop because you have given up cultivating immortals - after all, it is a potential disaster, and direct annihilation is the safest. Therefore, even in order to save your own life, you must cultivate hard. ”

Zhang Luxin said Damn, this is the motivation for me to find out how to practice, it seems that I have to cultivate immortals in this life...... There's no way, then let's cultivate-"Okay, let me return to Zhongding, and from now on, I won't go down the mountain again, and concentrate on cultivation." ”

Who wants Zhang Jian to shake his head: "Cultivation is not only self-cultivation, but also heart cultivation, sitting all day long, it is useless in your heart." Before Fang Caiwu appeared, Xuanren wanted you to go to Jiangdong to visit Yuji, and you can still visit now. ”

Zhang Lu said that this can't be done, there is Pei Xuanren guarding in Zhongding, maybe it is not easy to kill me, once I go down the mountain, am I not extremely dangerous? Zhang Jian said that without hardships and dangers, how can I hope to achieve the Tao? Besides, Pei Xuanren's ascension is imminent, and after he ascends to the immortal, you can only rely on yourself to protect yourself-"I also have important things to do, and An Ke will accompany you for a long time?" "Just look at your eyes to know what you are thinking, and you must always bring an immortal as a bodyguard by your side, you can't help but think too beautiful!

Immediately, he comforted Zhang Lu again, saying that you can rest assured, according to your description, you must use the body of a mortal in the mortal world to attack you, and it should not be difficult to deal with. I will teach you some ways to deal with it directly, and send a soul to you, if you are really in danger and cannot save your life on your own, I will also immediately come to your help, even if you are highly expected by the heavenly realm, this benefit will still be given to you. And when I go to Jiangdong, I will find a few more people to help you......
